Replacing the Osterizer as standard lab equipment
03/19/12 — After a year in Asia and South America visiting research labs that lacked the basics, Lina Nilsson - a post-doctoral researcher in the bioengineering lab of professor Daniel Fletcher - and a team of engineering colleagues brainstormed about how to develop low-cost, accessible tools that could produce research-grade results. The team evolved into Tekla Labs, a cooperative of ten partners from Berkeley Engineering and UCSF. Their idea won first place for social entrepreneurship in the 2010-11 Big Ideas @ Berkeley contest.
Computers implanted in brain could help paralyzed
12/27/11 San Francisco Chronicle — It sounds like science fiction, but scientists around the world are getting tantalizingly close to building the mind-controlled prosthetic arms, computer cursors and mechanical wheelchairs of the future. Jose Carmena, a neuro-engineer at UC Berkeley and co-director of the Center for Neural Engineering and Prostheses at Berkeley and UCSF, puts his thoughts succinctly: "There's going to be an explosion in neural prosthetics."
Computer scientists may have what it takes to help cure cancer
12/05/11 The New York Times — Berkeley Engineering professor David Patterson discusses how computer scientists will fight the war on cancer by taking on the Big Data challenges of information processing, genome sequencing, cloud computing, crowd-sourcing and other complex tasks. Patterson argues, "Given that millions of people do have and will get cancer, if there is a chance that computer scientists may have the best skill set to fight cancer today, as moral people aren't we obligated to try?"
An ergonomic retrofit
11/29/11 — The Memorial Stadium seismic retrofit project necessitates boring some 40,000 holes into concrete foundations with drills weighing up to 45 pounds-potentially exposing drill operators to the harmful effects of muscle injury, dust, and vibration exposure. “These workers typically have pain and fatigue in the wrists, shoulders and back; some have also experienced damage to the nerves in the fingers,” says David Rempel, bioengineering professor and director of the Ergonomics Program in UC's Center for Occupational and Environmental Health. The Ergonomics Program has been designing ways to minimize the adverse health effects of such labor on workers.
The partnership at the heart of heart-monitoring technology
11/25/11 The Atlantic — We have the diagnostic tools to monitor our hearts thanks to the work of two creative and persistent men, Berkeley Engineering alumnus Bruce Del Mar (B.S.'37 ME) and Norman "Jeff" Holter. Their collaboration, which spanned two decades, produced a commercially viable heart monitor known as the Holter Monitor Test.
The brittleness of aging bones – more than a loss of bone mass
08/29/11 Berkeley Lab — New research at Berkeley shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss of quantity in the susceptibility of bone to fracturing. Using a combination of x-ray and electron based analytical techniques as well as macroscopic fracture testing, the researchers showed that the advancement of age ushers in a degradation of the mechanical properties of human cortical bone over a range of different size scales. "In characterizing age-related structural changes in human cortical bone at the micrometer and sub micrometer scales, we found that these changes degrade both the intrinsic and extrinsic toughness of bone," says Berkeley Engineering materials scientist Robert Ritchie.
Going with the flow
06/07/11 — A major milestone in microfluidics could soon lead to stand-alone, self-powered chips that can diagnose diseases within minutes. Working as part of an international team of researchers, Berkeley engineers have developed a device that is able to process whole blood samples without the use of external tubing and extra components. “This is a very important development for global healthcare diagnostics,” says bioengineering professor Luke Lee, the study's principal investigator. “Field workers would be able to use this device to detect diseases such as HIV or tuberculosis in a matter of minutes.”
Of mice and livers
05/04/11 — Humans and mice have more in common than just an affinity for cheese. The two mammals share about 99 percent of their genes, making mice a useful model for studying human health and disease. There are, however, stark differences between their livers, the organ that removes metabolized drugs from the blood. When it comes to drug trials, this can create problems, as testing on mice often fails to accurately show a drug's toxicity to humans. But Alice A. Chen (B.S'03 BioE) has devised a technology that could result in faster, safer and more efficient drug development. She has created a humanized mouse with a tissue-engineered human liver, allowing researchers to predict how a new drug could affect humans at a much earlier point in the development process.
How to measure an oil spill
02/02/11 — When oil was flowing from BP's broken well at the bottom of the Gulf of Mexico last spring, the company estimated the flow rate at about 1,000 barrels a day. But news outlets wanted an independent estimate. Could Ömer Savaş, an expert in fluid mechanics and turbulent flows, help? Soon Savaş became involved in a national effort to establish the “official” flow rate, a number that would dictate not only the level of resources assigned to the cleanup but also its legal ramifications once the emergency had passed.
Engineers make artificial skin out of nanowires
12/24/10 Printed Electronics World —
Engineers at UC Berkeley have developed a pressure-sensitive electronic material from semiconductor nanowires that could one day give new meaning to the term "thin-skinned." "The idea is to have a material that functions like the human skin, which means incorporating the ability to feel and touch objects," said Ali Javey, associate professor of electrical engineering and computer sciences and head of the UC Berkeley research team developing the artificial skin, dubbed "e-skin."
Energizing the energy agenda
12/14/10 — While climate change and carbon emissions are very much in today's headlines, what is less often discussed is the need to provide technological societies with the economic imperative to make changes in our global energy system.
Wheels of change in South Africa
12/14/10 — More than 9 million South African children walk to school every day. Three million walk for more than an hour, and in the rural countryside, some walk more than four hours. “It's madness,” says Louis de Waal (M.S'72 CEE), who grew up in rural South Africa and spent his professional life designing and building thousands of kilometers of roads there, many of which opened up inaccessible places deep in the country's interior. Now retired, De Waal is on a mission to improve mobility for all South Africans, especially in rural areas. The goal, says the 73-year-old Cape Town resident, is to keep children in school and help adults reach work more easily, ultimately easing poverty and slowing the flood of people forced to move to urban areas for work.
Silent and deadly: Smoke from cooking stoves kills poor people
09/23/10 The Economist — The appeal of a stove that produces more heat, more cleanly and with less fuel is clear. But Kirk Smith, a stove specialist at UC Berkeley, points out that most efforts to promote cleaner stoves have flopped. Too much emphasis has gone on technology and talking to people at the top, too little to consulting the women who actually do the cooking. Another lesson of past failures, says UC Berkeley professor Daniel Kammen, who runs the World Bank's clean-energy programs, is the need for better data about how stoves are actually used
UC Berkeley researchers study health effects of 3D
08/29/10 ABC News — More 3D movies than ever are in theaters now and manufacturers are selling 3D TVs. Yet surprisingly little is known about the effects of stereo vision on our brains. Researchers at Berkeley are applying cutting-edge technology to find out what happens when 3D is not produced correctly. UC Berkeley Visual Science Professor Martin Banks' lab is breaking new ground in studying the way we perceive depth. Enabling test subjects to see two screens at once using mirrors, his team has established some of the things that lead to bad 3D
